A particle is moving eastwards with a velocity of 5m/s. In 10s the velocity changes to 5m/s northwards. Find the average accelration is this time

Text Solution

Verified by Experts

`veca_(av) = (vec(Deltav))/(DeltaT)=(vecv_(f)-vecv_(i))/(Deltat)`

`veca_(av)=(5hat(j)-5hat(i))/(10)=(5sqrt(2))/(10)=(1)/(sqrt(2))"m/s"^(2)`. North-west direction.
